| Abstract: |
| From the calibration study of the determination of alfalfa soil moisture with neutron probe,we got three calibration equations,which were y=82.772x-3.007(R2=0.9353,R=0.9671) for 20～60 cm soil layer, y=77.822x+0.1032(R2=0.8283,R=0.9101) for 60～120 cm soil layer,and y=83.327x-2.2304(R2=0.8871,R=0.9419) for 120～200 cm soil layer.Average relative error of neutron probe method was 0.81% in comparison with oven drying method.This proved that it was feasible to determination soil moisture with neutron probe instead of oven drying method. |
